The Low Profile Design with 45° Bend Disconnects Fuel Line, EVAP Line Fittings and DEF Fittings in Hard-to-Reach Areas. Disconnects fuel line, EVAP line and DEF fittings with tabs that must be depressed to disengage. Low-profile design with 45° bend allows the tool to fit between the top of the fuel tank and vehicle. Works great on Delphi two tab connectors and some import vehicles. Can also be used on some electrical connectors.
